Hypothesis
Can the platysma motor branch be effectively used as a donor for nerve transfer in brachial plexus injuries?
Conclusion
The platysma motor branch is a promising donor nerve for brachial plexus repair, showing no deficits after its use.
Supporting Evidence
- The patient recovered 45° of shoulder abduction and full elbow flexion eight years post-surgery.
- No deficits were observed in the function of the platysma muscle after its section.
- The patient was able to use his limb for daily activities after the surgery.
Takeaway
Doctors can use a part of a neck muscle to help people who hurt their arm nerves, and it seems to work well without causing problems.
Methodology
The patient underwent nerve transfers involving the accessory nerve, hypoglossal nerve, and platysma motor branch to restore function.
Limitations
Only one case is reported, limiting generalizability.
Participant Demographics
A 21-year-old male with complete brachial plexus avulsion.
